  2. Aqara - FP2 Presence Sensor- mmWave Radar Sensor, Zone Positioning, Multi-Person and Fall Detection, Sleep Monitoring - White - Front_Zoom
    Top comment

    "There is also a built in light sensor that can detect light levels, which can then be used in automations. ...For other Home Assistant users like myself, you simply need to set up the device, use Aqara's app to define your zones, then use the Homekit Controller integration to pair the sensor to Home Assistant. After that it'll pull in occupancy sensors for each zone as well as a light level sensor (which I use to NOT turn on the lights during bright daytime). "

    Product Description

    Aqara Presence Sensor FP2 uses cutting-edge millimeter-wave radar technology, which can accurately detect the presence of people even with slight movements. This technology ensures continuity and stability of the smart device. It also has the function of zone positioning, which allows for the automation of different conditions in different zones, such as beds and tables. One space can now be divided into up to 30 small zones and recognize up to five targets (Multi-person Detection). It can also control other smart home devices through ecosystems such as Apple Home to achieve wider applications. It features functions such as human fall recognition, sleep monitoring and a built-in light sensor. Likewise, it is a great helper that can truly combine the diversity of the user's home life and realize the automation of different personalities.
